Method:
To make the filling:
Pressure cook the potatoes. Peel the skin and mash well.
Heat oil in a pan. Add jeera. When it crackles, Add chopped garlic and fry for a minute.
Add rest of the ingredients and mix well. Fry for 2-3 minutes. The mixture should be dry.

To assemble:
Thaw the wrappers.
Place some potato filling in the center.
Lightly wet the open edges of the wrapper with a drop of water and fold it into a triangle. Seal well.
Repeat these steps for other wrappers.
Deep fry the samosas till golden brown.
Serve hot with chutney or ketchup.

Truly easy. I never attempted to make samosas till date. Each time I have a samosa craving, I look up some recipe, but never make it just because it is so complicated to cook samosas from scratch. Thanks for the great idea :-)
